What is CPU and its function?

The computer’s central processing unit (CPU) is the portion of a computer that retrieves and executes instructions. The CPU is essentially the brain of a CAD system. It consists of an arithmetic and logic unit (ALU), a control unit, and various registers. The CPU is often simply referred to as the processor.

What is Motherboard PPT?

INTEGRATED MOTHERBOARD An integrated system board has multiple components integrated into the board itself. These may include the CPU video card , sound card and various controller cards. 6. NON INTEGRATED MOTHERBOARD Non integrated system board uses installable components and expansion cards.

What are the 5 functions of CPU?

Functions of CPU in computer:

• Controlling all other parts of the machine and sending timing signals.
• Transferring data between memory and I/O devices.
• Fetching data and instructions from memory.
• Decoding instruction.
• Performing arithmetical and logical operations.
• Executing programs stored in memory.

What are the types of central processing unit?

Types of CPU

• Single-core CPU. It is the oldest type of CPU which is available and employed in most of the personal and official computers.
• Dual-core CPU.
• Quad-core CPU.
• Hexa Core processors.
• Octa-core processors.
• Deca-core processor.

How does a central processing unit work?

The CPU performs calculations, makes logical comparisons and moves data up to billions of times per second. It works by executing simple instructions one at a time, triggered by a master timing signal that runs the whole computer.

Which are the main part of central processing unit?

The CPU is made up of three main components, the control unit , the immediate access store and the arithmetic and logic unit .

What is Ram PPT?

RAM(Random Access memory) is a volatile memory. RAM is our working memory storage. All the data, which the PC uses and works with during operation, are stored here. Data are stored on drives, typically the hard drive.

What are the two main functions of the CPU?

The CPU is regarded as the computer’s brain. The CPU is responsible for all data processing operations. It saves information such as data, intermediate results, and instructions (program). It directs the operation of all computer components.

What are the main components of CPU?

The central processing unit (CPU) consists of six main components:

• control unit (CU)
• arithmetic logic unit (ALU)
• registers.
• cache.
• buses.
• clock.

What are the types of motherboard?

Motherboards come in three main sizes, from largest to smallest: ATX, Micro-ATX and Mini-ITX (Yes, Mini is smaller than Micro). You can use a smaller chassis with the micro or mini boards, but you’ll have to settle for fewer PCIe slots, RAM slots and other connectors.
